Study Notes
- Simple Face Mask delivers a flow of continuous oxygen.
- Delivers oxygen concentrations of 28-50% at a flow rate of 5-10 LPM.
- Indicated for mild to moderate respiratory distress.
- The partial rebreather mask delivers higher concentrations of oxygen than a simple mask.
- Delivers oxygen at concentrations of 40-70% at a flow rate of 5-15 LPM.
- Indications: hypoxia, respiratory disease, cardiac disease, shock, trauma, severe blood loss, seizures.
- Non-Rebreather Mask delivers high concentrations of oxygen.
- Oxygen is not diluted by exhaled or atmospheric air.
- It delivers close to 80-100% oxygen at a flow rate of 12-15 LPM.
- Use for unassisted breathing patients, those needing assistance require mechanical ventilation.
- Indications: severe physical trauma, carbon monoxide poisoning, smoke inhalation, chronic airway obstruction.
- The venturi or air-entrainment mask is a high flow device.
- Delivers a fixed oxygen concentration of 24% to 50%.
- Appropriate for patients with a hypoxic drive who need supplemental oxygen.
- Used for those with chronic obstructive pulmonary disease (COPD).
- Prevents O2 Toxicity for patients with chronic respiratory diseases.
